Abstract
A novel method of manufacturing thick foams, especially molded thick foams useful as tissue scaffolds and other medical devices. Also disclosed are novel thick foams made using the process of the present invention, wherein such thick foams may be used as medical devices or components of medical devices.
Claims18
A method of making a thick polymer foam, comprising the steps of:
- providing a thermoreversible polymer solution, said solution comprising a biocompatible, biodegradable polymer and a solvent;
- cooling the solution until the solution gels;
- and.
- removing the solvent by lyophilization to yield a thick foam member having inter-connected pores.

A foam member, comprising:
- a foam member having inter-connected pores, wherein the foam member has a thickness of greater than about 1 cm, and wherein the foam member is manufactured by a process, comprising:
- providing a thermoreversible polymer solution, said solution comprising a biocompatible, biodegradable polymer and a solvent;
- cooling the solution until the solution gels;
- and,
- removing the solvent by lyophilization to yield a thick foam member having inter-connected pores.
